> I am compiling on Windows.
idl-compiler.out and idl-compiler.err files in the dir from which you ran the build.
The error file says "Error: Could not find or load main class org.jacorb.idl.parser". I tried adding the idl.jar file in the build path but it still fails with the same error.
Maybe it is some path issue on windows as idl.jar does contain the required class.
I do know that the next revision of JBoss Transactions (known as Narayana https://github.com/jbosstm/narayana) does build OK on Windows., possibly because we replaced the Ant build system with Maven. We are set to release 5.0.0.M2 next week, I would encourage you to hold off till then and try the 5.0.0.M2 version (note: the tests don't run on Windows due to some *nix specific result checking).
